Delhi buildings install anti-smog guns ahead of deadline

In Delhi, India, many big buildings like offices, hotels, and hospitals have put in special machines called anti-smog guns to help clean the air.

The government said these buildings had to do this by November 29.

So far, 149 buildings have done it, but there are more that need to.

These machines spray water to stop smog, which is like a thick fog that makes the air dirty.

The government will check if all the buildings have done this and might punish those that didn't.

The machines have to stay on all year, except when it's raining a lot.

Smaller buildings and homes don't have to do this.
